Description
Antikoagulerende midler er anvendbare terapeutiske midler ved farmakologisk behandling av f.eks. akutt, dyp venøs trombose, pulmonar embolisme, akutt, arteriell emboliser-ing av ekstremitetene, myocarddalt infarkt og utbredt intra-vaskulær koagulering. Profylaktisk administrering av antikoagulerende midler er antatt å forhindre en gjentagelse av embolisme i pasienter med reumatisk eller arteriosclerotisk hjertesykdom og forhindre visse tromboemboliske komplika-sjoner ved kirurgi. Administrering av antikoagulerende midler er også blitt indikert ved behandling av koronar arterie og cerebrovaskulær sykdom. Arteriell trombose, spesi-elt i arteriene som supplerer hjertemuskelen og hjernen, er en førende årsak til død.
Hirudin er et 65 rests polypeptid isolert fra spytt-kjertlene av igler. Det er et antikoagulerende middel som er en trombinspesifikk inhibitor. Selv om det er relativt kraftig, synes den kliniske bruk av hirudin isolert fra igle-ekstrakter, å være lite sannsynlig på grunn av dets begrensede mengde, kostbarhet og allergiske reaksjoner som vanligvis følger administrering av ethvert fremmed protein av denne størrelse.
Det er nå funnet en spesifikk region av hirudin som er ansvarlig, i det minste delvis, for dets antikoagulerende aktivitet. Denne region er blitt kjemisk syntetisert, og visse av dets analoger synes å bindes til gjenkjennelsesstedet av trombin, men ikke det enzymatiske spaltningssted som er rommessig adskilt. Binding av de syntetiske peptider forhindrer konkurrerende binding av fibrinogenet til gjenkjennelsesstedet for trombin, en forutsetning for fibrin-produksjon og klumpdannelse. Peptidene ifølge oppfinnelsen utviser signifikant antikoagulerende aktivitet, og deres uvanlige evne til å binde bare til gjenkjennelsesstedet uten binding til splittingsstedet av trombin kan utgjøre et viten-skapelig interessant og terapeutisk signifikant supplement til den antikoagulerende terapi.
Oppfinnelsen angår således en analogifremgangsmåte for fremstilling av terapeutisk aktive peptidderivater av formel

Uttrykket "lipofil aminosyre" innbefatter Tyr, Phe, L3U, Nie, Ile, Val, His og Pro.
De naturlige aminosyrer med unntak av glycin, inne-holder et chiralt carbonatom. Med mindre annet spesifikt er angitt, er de optisk aktive aminosyrer det her henvises til, av L-konfigurasjon. Eksempelvis kan enhver av aminosyrene av eller A^-gruppen være av D- eller L-konfigurasjon. Som vanlig er strukturen av peptidene skrevet ut her slik at aminoenden er på venstre side av kjeden og carboxy-enden på høyre side av kjeden.
Polypeptidene av formel 1 kan danne farmasøytisk akseptable salter med enhver ikke-toksisk, organisk eller uorganisk syre. Eksempler på uorganiske syrer som danner egnede salter, innbefatter saltsyre, hydrobromsyre, svovel-syre og fosforsyre og sure metallsalter slik som natrium-monohydrogenorthofosfat og kaliumhydrogensulfat. Eksempler på organiske syrer som danner egnede salter, innbefatter mono-, di- og tricarboxylsyrer. Eksempler på slike syrer er f.eks. eddiksyre, glycolsyre, melkesyre, pyruvsyre, malonsyre, ravsyre, glutarsyre, fumarsyre, eplesyre, vin-syre, sitronsyre, ascorbinsyre, maleinsyre, hydroxymalein-syre, benzosyre, hydroxybenzosyre, fenyleddiksyre, kanel-syre, salicylsyre, 2-fenoxybenzosyre og sulfonsyrer slik som methansulfonsyre og 2-hydroxyethansulfonsyre. Salter av den carboxyterminale aminosyredel innbefatter de ikke-toksiske carboxylsyresalter dannet med enhver egnet uorganisk eller organisk base. Eksempelvis innbefatter disse salter de med alkalimetaller, slik som f.eks. natrium og kalium; jordalkalimetaller slik som calcium og magnesium; lette metaller fra gruppe HIA innbefattende aluminium; og organiske primære, sekundære og tertiære aminer slik som f.eks. trialkylaminer, innbefattende triethylamin, procain, dibenzylamin, 1-ethenamin, N,N<1->dibenzylethylendiamin, dihydroabietylamin, N-(lavere)alkylpiperidin og ethvert annet egnet amin.
Analogifremgangsmåten ifølge oppfinnelsen er kjenne-tegnet ved at peptidderivatene fremstilles ved fast fase-blokksyntese ved at en egnet, beskyttet aminosyre av formel A1 bindes til en aktivert harpiksbærer, hvoretter de andre alfa-amino-beskyttende aminosyrer fra A2 til A10 bindes til den terminale aminogruppe av den voksende peptidkjede som i mellomtiden er blitt avdekket ved fjerning av dens aminobeskyttende gruppe.
Ved denne prosedyre bindes en a-aminobeskyttet aminosyre til en. harpiksbærer. Den anvendte harpiksbærer kan være en hvilken som helst egnet harpiks hensiktsmessig anvendt innen faget for fast fase-fremstilling av polypeptider, fortrinnsvis polystyren som er blitt tverrbundet med fra 0,5 til 3% divinylbenzen, som enten er blitt klormethylert eller hydroxymethylert for å tilveiebringe steder for esterdann-else med den opprinnelig innførte ct-aminobeskyttede aminosyre .
Et eksempel på en hydroxymethylharpiks er beskrevet
av Bodanszky et al., Chem. Ind. (London) 38_, 1597-98 (1966). En klormethylert harpiks er kommersielt tilgjengelig fra
Bio Rad Laboratories, Richmond, California, og fremstill-ingen av en slik harpiks er beskrevet av Stewart et al., "Solid Phase Peptide Synthesis" (Freeman & Co., San Fran-cisco 1969), kapittel 1, s. 1-6. Den beskyttede aminosyre bindes til harpiksen ved prosedyren ifølge Gisin, Heiv.
Chem. Acta, 5_6 , 1476 (1973) . Mange harpiksbundne,
beskyttede aminosyrer er kommersielt tilgjengelige. For å fremstille et polypeptid ifølge oppfinnelsen hvori den carboxyterminale ende er en Thr-rest, kan eksempelvis et tert-butyloxycarbonyl- (Boe) beskyttet Thr bundet til en benzylert, hydroxymethylert fenylacetamidomethyl- (PAM) harpiks anvendes, og denne er kommersielt tilgjengelig.
Etter kobling av den oc-aminobeskyttede aminosyre til harpiksbæreren, fjernes den beskyttende gruppe under anvendelse av hvilken som helst egnet prosedyre slik som ved anvendelse av trifluoreddiksyre i methylenklorid, trifluoreddiksyre alene eller HC1 i dioxan. Avbeskyttelsen utføres ved en temperatur på mellom 0°C og romtemperatur. Andre standard spaltningsreagenser og betingelser for fjerning av spesifikke a-aminobeskyttende grupper kan anvendes. Etter fjerning av den a-aminobeskyttende gruppe kobles de andre aminobeskyttede aminosyrer trinnvis i den ønskede rekkefølge. Alternativt kan multiple aminosyre-grupper kobles ved oppløsningsmetoden før kobling med den harpiksopplagrede aminosyresekvens.
Den a-aminobeskyttende gruppe anvendt med hver aminosyre innført i polypeptidsekvensen, kan være en hvilken som helst beskyttende gruppe velkjent innen faget. Blant klassene av a-aminobeskyttende grupper som tas i betraktning, er (1) acyltype-beskyttende grupper slik som: formyl, tri-fluoracetyl, fthalyl, toluensulfonyl (tosyl), benzensul-fonyl, nitrofenylsulfenyl, tritylsulfenyl, o-nitrofenoxy-acetyl og a-klorbutyryl; (2) aromatiske urethantype-beskyttende grupper slik som benzyloxycarbonyl og substituert benzyloxycarbonyl slik som p-klorbenzyloxycarbonyl, p-nitrobenzylcarbonyl, p-brombenzyloxycarbonyl, p-methoxy-benzyloxycarbonyl, 1-(p-bifenylyl)-1-methylethoxycarbonyl, a,a-dimethyl-3,5-dimethoxybenzyloxycarbonyl og benzhydryloxy-carbonyl; (3) alifatiske urethanbeskyttende grupper slik som tert-butyloxycarbonyl (Boe), diisopropylmethoxycarbonyl, isopropyloxycarbonyl, ethoxycarbonyl og allyloxycarbonyl; (4) cycloalkylurethantype-beskyttende grupper slik som cyclopentyloxycarbonyl, adamantyloxycarbonyl og cyclohexyl-oxycarbonyl; (5) thiourethantype-beskyttende grupper slik som fenylthiocarbonyl; (6) alkyltype-beskyttende grupper slik som trifenylmethyl (trityl) og benzyl; og (7) tri-alkylsilangrupper slik som trimethylsilan. Den foretrukne a-aminobeskyttende gruppe er tert-butyloxycarbonyl.
Valg av et egnet koblingsreagens fører til den kjente teknikk. Et særlig egnet koblingsreagens hvor aminosyren som skal adderes er Gin, Asn eller Arg, er N,N-diisopropyl-carbodiimid og 1-hydroxybenzotriazol. Anvendelse av disse reagenser forhindrer nitril- og lactamdannelse. Andre koblingsmidler er (1) carbodiimider (f.eks. N,N<1->dicyclo-hexylcarbodiimid og N-ethyl-N'-(7-dimethylaminopropylcarbo-diimid); (2) cyanamider (f.eks. N,N-dibenzylcyanamid); (3) keteniminer; (4) isoxazoliumsalter (f.eks. N-ethyl-5-fenyl-isoxazolium-3 *-sulfonat); (5) monocykliske, nitrogen-holdige, heterocykliske amider av aromatisk karakter inneholdende 1 til 4 nitrogener i ringen slik som imidazolider, pyrazolider og 1,2,4-triazolider. Spesifikke heterocykliske amider som er anvendbare, innbefatter N,N'-carbonyldiimidazol og N,N-carbonyl-di-l,2,4-triazol; (6) alkoxylert acetylen (f.eks. ethoxyacetylen); (7) reagenser som danner et blandet anhydrid med carboxyIdelen av aminosyren (f.eks. ethylklorformiat og isobutylklor-formiat) eller det symmetriske anhydrid av aminosyren som skal kobles (f.eks. Boc-Ala-O-Ala-Boc) og (8) nitrogen-holdige, heterocykliske forbindelser som har en hydroxygruppe på et ringnitrogen (f.eks. N-hydroxyfthalimid, N-hydroxy-succinimid og 1-hydroxybenzotriazol). Andre aktiverende reagenser og deres anvendelse i peptidkobling er beskrevet av Kapoor, J. Pharm. Sei., _59, s. 1-27 (1970). Søkeren foretrekker anvendelse av det symmetriske anhydrid som koblingsreagens for alle aminosyrer bortsett fra Arg, Asn og Gin.
Hver beskyttet aminosyre eller aminosyresekvens inn-føres i fast fase-reaktoren i et ca. firedobbelt overskudd, og koblingen utføres i et medium av dimethylformamid: methylenklorid (1:1) eller i dimethylformamid alene, eller fortrinnsvis methylenklorid alene. I tilfeller hvor ufull-stendig kobling finner sted, gjentas koblingsprosedyren før fjerning av den a-aminobeskyttende gruppe, før kobling av neste aminosyre i fast fase-reaktoren. Vellykketheten ved koblingsreaksjonen ved hvert trinn av syntesen overvåkes ved ninhydrinreaksjonen som beskrevet av E. Kaiser et al., Ana lyt. Biochem. 34.' 595 (1970) .
Etter at den ønskede aminosyresekvens er blitt erholdt, fjernes peptidet fra harpiksen. Dette kan utføres ved hydrolyse slik som ved behandling av det harpiksbundne polypeptid med en løsning av dimethylsulfid, p-cresol og thiocresol i fortynnet vandig hydrofluorsyre.
Som kjent innen faget vedrørende fase fase-peptid-syntese, bærer mange av aminosyrene funksjonaliteter som krever beskyttelse under kjedefremstillingen. Anvendelse og valg av den egnede beskyttende gruppe hører til fagmannens kunnskap og vil avhenge av den aminosyre som skal beskyttes og nærvær av andre beskyttede aminosyrerester på peptidet. Valg av en slik sidekjedebeskyttende gruppe er kritisk ved at den må være en som ikke fjernes ved splitting under splitting av den beskyttende gruppe av a-aminodelen. - Eksempelvis er egnede sidekjede-beskyttende grupper for lysin benzyloxycarbonyl og substituert benzyloxycarbonyl, hvilken substituent er valgt fra halogen (f.eks. klor, brom, fluor) og nitro (f.eks. 2-klorbenzyloxycarbonyl, p-nitrobenzyloxy-carbonyl, 3,4-diklorbenzyloxycarbonyl), tosyl, t-amyloxy-carbonyl, t-butyloxycarbonyl og diisopropylmethoxycarbonyl. Den alkoholiske hydroxygruppe av threonin og serin kan beskyttes med en acetyl-, benzoyl-, tert-butyl-, trityl-, benzyl-, 2,6-diklorbenzyl- eller benzyloxycarbonylgruppe. Den foretrukne beskyttende gruppe er benzyl.
Disse grupper kan fjernes ved prosedyrer velkjente innen faget. Typisk foretas fjerning av beskyttende grupper etter at peptidkjedesyntesen er fullført, men de beskyttende grupper kan fjernes ved et hvilket som helst annet egnet tidspunkt.
Den antikoagulerende dose av et peptidderivat fremstilt ifølge oppfinnelsen er fra 0,2 mg/kg til 250 mg/kg kroppsvekt pr. dag avhengig av pasienten, strengheten av den trombotiske tilstand som skal behandles og det valgte peptidderivat.
Den egnede dose for en bestemt pasient kan lett bestemmes. Fortrinnsvis vil fra 1 til 4 daglige doser administreres, typisk med fra 5 mg til 100 mg aktiv forbindelse pr. dose.
Antikoagulerende terapi er indikert for behandling
og forhindring av et utall av trombotiske tilstander, i særdeleshet koronar arterie og cerebrovaskulær sykdom. Fag-mannen er velkjent med omstendigheter som krever antikoa-
gulerende behandling. Med uttrykket "pasient" anvendt her, menes pattedyr slik som primater, innbefattende mennesker, sauer, hester, kveg, griser, hunder, katter, rotter og mus.
Selv om enkelte av peptidderivatene kan overleve passasje gjennom tarmen etter oral administrering, er ikke-oral administrering foretrukket, f.eks. subkutan, intra-venøs, intramuskulær eller intraperitoneal; administrering ved depotinjeksjon; ved implantatpreparat; eller ved påføring på slimhinner, slik som i nese, svelg og bronchialkanaler, eksempelvis i en aerosol inneholdende et peptidderivat ifølge oppfinnelsen i form av spray eller tørt pulver.
For parenteral administrering kan forbindelsene administreres som injiserbare doser av en løsning eller sus-pensjon av forbindelsen i et fysiologisk akseptabelt fortynn-ingsmiddel med en farmasøytisk bærer som kan være en steril væske slik som vann og oljer, med eller uten tilsetning av et overflateaktivt middel og andre farmasøytisk akseptable hjelpestoffer. Eksempler på oljer som kan anvendes i disse preparater, er petroleumoljer, og de av animalsk, vegetabilsk eller syntetisk opprinnelse, f.eks. peanøttolje, soyabønne-olje og mineralolje. Generelt er vann, saltvann, vandig dextrose og beslektede sukkerløsninger, ethanol og glycoler slik som propylenglycol eller polyethylenglycol, foretrukne væskeformige bærere, i særdeleshet for injiserbare løsninger.
Forbindelsene kan administreres i form av en depotinjeksjon eller implantatpreparat som kan formuleres på en slik måte at det muliggjøres en forsinket frigivelse av den aktive bestanddel. Den aktive bestanddel kan være presset til pellets eller små sylindre og implanteres subkutant eller intramuskulært som depotinjeksjoner eller implantater. Implantater kan anvende inerte materialer slik som bioned-brytbare polymerer eller syntetiske silikoner, f.eks. "Silastic", silikongummi fremstilt av Dow-Corning Corporation.
Oppfinnelsen illustreres nærmere i de etterfølgende eksempler.

Fremstilling av H- Gly- Asp- Phe- Glu- Glu- Ile- Pro- Glu- Glu- Tyr-Leu- Gln- OH
Peptidet ble syntetisert ved fast fase-metoder under anvendelse av 0,1 mmol av en 0,66 mmol/g Boc-Gln-PAM-harpiks. Doble symmetriske anhydridkoblinger ble utført med 2,0 mmol Na-Boc-aminosyre (Peptides International) bortsett fra Boc-Gln som ble koblet med DCC/HOBT-metoden. Den anvendte sidekjedebeskyttelse var: Asp(Chx), Glu(Bzl), Tyr(2-BrZ). Etter endt syntese ble Na-Boc-beskyttelsen fjernet med 50% trifluoreddiksyre i methylenklorid. Harpiksen ble vasket tre ganger med methylenklorid, ble nøytralisert med tre vask-inger med 10% diisopropylethylamin i methylenklorid, ble vasket tre ganger med methylenklorid og tørket i vakuum. Peptidet ble avbeskyttet og spaltet fra harpiksen med HF inneholdende 2% anisol ved 0°C i 35 minutter. HF ble fjernet i vakuum ved 0°C, peptidet ble utfelt med ethylether, ble ekstrahert fra harpiksen med 30% vandig eddiksyre og lyofilisert.
Peptidet ble renset ved avsaltning på en 92 x 2,6 cm Sephadex<®> G-15 kolonne i 5% vandig eddiksyre og ble lyofilisert. Preparativ HPLC ble utført på en C 18 Vydac® 218TP1010 (250 x 10 mm) kolonne med 24% acetonitril i 0,1% vandig trifluoreddiksyre ved 5 ml/min. Hovedtoppen ble opp-samlet og lyofilisert under dannelse av 101 mg av det ønskede produkt (58% utbytte basert på startharpikssubstitusjon). Homogenitet ble bestemt ved HPLC og TLC. HPLC "Vydac"
